Limited distribution permitted only to teachers and educators for course. Assumptions 1 Atmospheric air behaves as an ideal gas.

If the density of air is 1. Assumptions 1 Both water and oil are incompressible substances. The tank’s pressure in various English units are to be determined.

Discussion Note that jumping horizontally from one tube to the next and realizing that pressure remains the same in the same fluid simplifies the analysis greatly. Hence, the weight is an extensive property.

Analysis The lower and upper limits of comfort range in C are C Parte 5 de 5 Properties The specific gravities of oil, mercury, and termoinamica are given to be 0. For the given specific gravities and fluid column heights, the gage pressure at A and the height of a mercury column that would create the same pressure at A are to be determined. Select New Parametric Table from the Tables menu.

Analysis The atmospheric pressure is determined directly from kPa Assumptions The variation of the density of the liquid with depth is negligible.

Using proper conversion factors, the unit cost of each steak is determined to be 12 ounce steak: Properties The density data are given in tabular form as 0 5 10 15 20 25 0 0. Choose Solve Table or press F3 from the Calculate menu.

It violates the second law of thermodynamics. Assumptions The property relation is valid over the entire region considered. Analysis The area upon which pressure 1 acts is 2 22 1 1 in For a constant volume of blood to be discharged by the heart, the blood pressure must increase to overcome the increased resistance to flow.

The ice point on this scale, and its relation to the Kelvin scale are to be determined. Assumptions 1 The weight of the person is distributed uniformly cenegl the imprint area of the shoes.

Analysis a Pressure change across a differential fluid layer of thickness dz in the vertical z direction edicino. The specific gravities of oil and mercury are given to be 0. Assumptions The density of air is constant throughout the room. The height termodinamiac the building is to be determined. Analysis The absolute pressure in the tank is determined from kPa This fatal level temperature change of body temperature is to be expressed in F, K, and R.

Discussion Note that sometimes the use of specific gravity offers great convenience in the solution of problems that involve several fluids. The rate of heat loss is to be expressed per F, K, and R of temperature difference between the indoor and the outdoor temperatures. Assumptions The steaks are of identical quality. You should get into the habit of never writing the unit lb, but always use either lbm or lbf as appropriate since the two units have different dimensions.

The mass and weight of the air in the room are to be determined. For a given pressure drop and brine level change, the area ratio is to be determined. Analysis The power needed for acceleration depends on the mass, velocity change, and time interval. The height that the blood will rise in the tube is to be determined. The local atmospheric pressure in that city is to be determined.

The specific gravity of oil is given to be 0. Discussion The final result could be expressed in various forms. It is the gage pressure that doubles when the depth is doubled. Assumptions Wind approaches the turbine blades with a uniform velocity.

This decrease in temperature is to be expressed in F, K, and R. Use the relationship between the pressure gage reading and the manometer fluid column height. Cegnel example of Pascals principle is the operation of the hydraulic car jack.

For a given vertical level difference, the gage pressure in the duct and the length of the differential fluid column are to be determined. The minimum imprint area per shoe needed to enable her to walk on the snow without sinking is to be determined. Set values of h to range from 0 to termodinamoca in steps of 0. Assumptions The air in the troposphere behaves as an ideal gas.

Therefore, the fatal level of hypothermia is a 5 K b A relation for the variation of density with elevation is to be obtained, the density at 7 km elevation is to be calculated, and the mass of the atmosphere using the correlation is to be estimated. The pressure difference between the two pipelines is to be determined.
